Answer 1

Part 1) The sandbox hold
`36\ ft^(3)`

Part 2) Jodi didn't buy enough sand to fill the sandbox.

Explanation:

Part 1)

How much will the sandbox hold?

we know that

The volume of the sandbox is equal to

`V=LWH`

substitute the given values

`V=(6)(5)(1.2)`

`V=36\ ft^(3)`

therefore

The sandbox hold
`36\ ft^(3)`

Part 2) Did Jodi purchase enough sand to fill the sandbox?

we know that

Jodi purchases 20 cubic feet of sand to fill the sandbox

Compare with the volume of the sandbox

`20\ ft^(3) < 36\ ft^(3)`

therefore

Jodi didn't buy enough sand to fill the sandbox.
